Hiawatha is a secure and advanced Web server for Unix. It has been written with security as its main goal. It features advanced access control, prevention of SQL injection and cross-site scripting, banning of clients who try such exploits, the ability to run CGIs under any UID/GID you want, and many other features. These features make Hiawatha an interesting Web server for those who need more security than what the other available Web servers are offering. Hiawatha is also fast and easy to configure.

RPL/2 (Reverse Polish Lisp/2) is a langage derived from the RPL made by Hewlett-Packard for its HP-28S. It has some extensions (preprocessor, compilated libraries, new functions), a TeX output, and can draw graphics.

wasora is a computational tool designed to aid a cognizant expert, whether an engineer, scientist, technician, or geek, to analyze complex systems by solving mathematical problems by means of a high-level plain-text input file containing algebraic expressions, data for function interpolation, differential equations, and output instructions amongst other facilities. At first glance, it may look like another high-level interpreted programming language, but it should be seen as a syntactically-sweetened way to ask a computer to perform a certain mathematical calculation. For example, the famous Lorenz system may be solved by writing the three differential equations in a human friendly plain text file.

aria2 is a utility for downloading files. The supported protocols are HTTP(S), FTP, BitTorrent, and Metalink. It has a powerful segmented downloading ability, downloading a file from multiple sources and multiple protocols and utilizing your download bandwidth to the maximum. It supports downloading a file from HTTP(S)/FTP and BitTorrent at the same time, while the data downloaded from HTTP(S)/FTP is uploaded to the BitTorrent swarm. Using Metalink's chunk checksums, aria2 automatically validates chunks of data
while downloading a file like BitTorrent.

pmcyg is a tool for creating customized collections of Cygwin packages together with the Cygwin installer. This enables self-contained distributions to be created without having to mirror the entire set of Cygwin packages. For example, it can create a single CD-ROM or DVD from which a personalized version of Cygwin can be installed on machines not connected to the Web. A basic installer can be created in less than 25MB; a full set of Cygwin packages might fill a DVD-ROM; or a selection of packages can be constructed to suit your chosen installation medium. pmcyg will then download these and all their dependencies automatically. pmcyg can be used either as a command-line script or via a simple graphical interface.

Geomview is an interactive program for creating,
viewing, and manipulating 3D and
higher-dimensional geometric objects. Geomview can
be used as a standalone viewer for static objects
or as a display engine for other programs which
produce dynamically-changing geometry.

Bandwidth is primarily a memory bandwidth benchmark, but it can also measure network bandwidth. It measures the maximum memory bandwidth of each part of the memory system, including main memory, L1, L2, and L3 caches, framebuffer memory, and register-to-register. For many tests, it performs both sequential memory accesses as well as random memory accesses to provide a more real-world performance estimate. The tests support Linux (Intel), Windows/Cygwin, and Mac OS X. Its core routines are in assembly for x86 and x86-64 architectures with both SSE4 and AVX support. Bandwidth also includes automatic graphing of the results, stored to a BMP image file. The network bandwidth tests support Linux, Mac OS X, and Windows/Cygwin.
